The thinner plates are installed only on the slopes of window and door proemov.Mineralnuyu cotton you can buy in the form of slabs and mats of different density and hardness. Mats usually rolled up and the slab with a few pieces are stacked in bundles, each weighing from 10 to 60 pounds and occupies the volume of about 0.3 m The most common sizes plates – 100 60 cm with a thickness of 5 or 10 cm mats may have a length of 2.9 meters, width of 50-120 cm and a thickness of 2-22 santimetrov.Osnovnye features slabs of mineral wool for insulation stenTeploprovodnost, W / (mK ) 0,036-0,042 Density, kg/m3 90 150Vodopogloschenie,% (for hydrophobized boards) 1.5 2Teploprovodnost, W / (mK) 0,029-0,033 Permeability (P), mg / (m h Pa) 0.30 Min.Vatoy Warming – the technology and steps: 1 Plates insulation is placed every 50-60 cm along the perimeter of the entire steny.2 In brick or block masonry laid special ankery.3 They skewer of mineral cotton plity.4 Then, using special clips to fiksiruyut.5 then begin to brick kladku.6 Facing bricks are laid, keeping a small gap between the joints with sand kirpichom.7 overwritten with a special masterka.8 Align joints with a trowel.

Have been investigated in experimental stands, and experienced dozens of turbines flow parts and hundreds of design options, enabling significantly increase the efficiency of the turbines of small power, and improve the compactness of 4, 8, 23, 30-32. Especially important at this stage was the joint work with troubled lab gas and steam Trubin Moscow Power Engineering Institute, headed by Corresponding Member. USSR prof. Hear other arguments on the topic with ISearch. AV Scheglyaevym and head of the gasdynamic Department of Laboratory – Prof.. ME Deich. The result of this collaboration was the creation of second-generation high-profile subsonic and supersonic turbine arrays and high-efficiency series turbine stages and compact flow parts.
Expanded the plant and significantly enhanced in connection with the manufacture of steam turbines driving shirokorezhimnyh study the dynamics of the rotors, blades and blade elements apparatus, made dozens of rotor blades and the hundreds in conditions as close to operational as well as direct-to-use, drastically reducing vibration and stabilize condition of turbines and rotors to increase reliability, blading and rotor blades. The reliability of the blades, for example, driven turbines increased to hundreds of thousands of hours between failures, and actual turbines – up to tens of thousands of hours. New structural forms required the use of modular rotors avtofretirovaniya drive and new technology of their elements, which in turn increased the dynamic stability of the rotor group. Dynamic studies of bearings helped solve the problem of creating the bearing assemblies with controllable (variable) dynamic stiffness, which expanded the range of drive turbines with flexible rotors.
The issue of roads and in particular road surface, in Russia has always been important. Very often, the quality of coating depends on the gravel in road construction, the quality of which is regulated by special guests. The main requirement – reduced to rubble mass of grains having a lamellar and needle shape to the allowed 10%. To date, the producers of crushed stone in Russia, including the largest ones, such as such as JSC "First Non-Metallic company "experienced a significant problem. The problem was that the gravel used in factories producing cone crusher crushed rock with lots of screenings. This resulted in an additional accumulation of a problem illiquid products and the need for recycling. Best rubble, having cuboid shape, today is produced using a centrifugal-impact technology.
By making a series of proprietary solutions in the standard process of CJSC "Ural-Omega" has created a centrifugal grinder allowing the rubble cubiform not only a given size, but with a minimum of waste, which then, the same mill can recycle the sand needed texture. Putting into operation at one of its businesses, Gumbeyskom plant for the production of crushed stone, centrifugal DC crushers manufactured by CJSC "Ural-Omega" has allowed Open Society "First Non-Metallic Company" to reduce the flakiness of the products to the established norms of 10%. On Gumbeyskom plant for crushed stone production was established not only centrifugal crusher DC – 1.6 has a capacity for production of 300 tons / hour. There has also been installed and successfully used in the manufacturing process classifies the set of CT allows to extract from screening products in the form of sand and gravel melkofraktsionnogo. This result made it possible for JSC "First Non-Metallic Company" begin the process of technological re-equipping its plants crushers and other equipment for grinding of rocks produced by CJSC "Ural-Omega". To date, the process of retooling the production is gaining momentum.
Sibirtsevsky, Sulina Kamnerechensky and production plants are equipped with ballast operating successfully DC centrifugal crusher required performance. Projected crushing complex, which is based on lies crusher DC – 1.6, for refitting a factory in Isetske which will be cubiform rubble. On near-term planned replacement of equipment at several factory complexes producing cubiform rubble, including Angalskom. Of course, improving the quality of gravel impact on improving the properties pavement. But keep in mind that the problem of bad roads addressed comprehensively. International standards must comply with everything from design to construction methods and Paving. At these conditions we will certainly have an excellent road, do not give way in Europe.
